Reference
Reference Control Philosophy (DOQ0000138-EN) and Sequence Diagram
(DOQ0000139-EN) for additional details on full-auto control programming. For
Semi-Auto options, reference IB Logic Diagram (DOQ0000159-EN) or EB Logic
Diagram (DOQ0000164-EN) for additional details.
Internal Backwash
The Internal Backwash sequence will take each Filter Station offline in sequence.
The Drain Valve will energize at the first Filter Station allowing the inlet of the
station to be connected to the Drain Header of the unit. Cleaning fluids are then
diverted from the Outlet Header to dislodge and discharge accumulated debris
collected on the outside of the Filter Element. The Filter Station is then placed
back online, and after a short pause, the sequence continues to the remaining
Filter Stations.
External Backwash
The External Backwash sequence will take each Filter Station offline in
sequence. The Drain Valve and Backwash will energize at the first Filter Station
allowing the inlet of the station to be connected to the Drain Header, and the
outlet of the station to be connected to the Backwash Header of the unit. The
Backwash Supply Valve will then open to supply cleaning fluid to the Backwash
Header. Cleaning fluids are then diverted from the Backwash Header to dislodge
and discharge accumulated debris collected on the outside of the Filter Element.
The Filter Station is then placed back online, and after a short pause, the
sequence continues to the remaining Filter Stations.
The system is controlled by an industrial controller housed in a NEMA rated
enclosure. An HMI touch panel display is used to communicate with the
controller.

MAIN SCREEN
The top of the main screen (Images 1 and 2) will display the status states of the
filter (Table 1). When the timed backwash function is activated it will show a
countdown to the next backwashing cycle in minutes. If the Backwash Interval
time setting is set to zero, this timer will be disabled and the TIMED BACKWASH
DISABLED message will be displayed (Image 6). If a manual or differential
pressure backwash cycle is performed the time interval will reset to the
Backwash Interval time setting. Below is a description of each button function on
the main screen.
A. The ON/OFF power button See warning box on the first
page. Turns the PLC ON and OFF. In the event of power failure, the
operator will have to turn the system back ON. To reset the system and
clear all error messages, turn the system OFF and back ON.
B. BACKWASH button Allows the operator to initiate a manual
backwashing sequence. When the button is touched, BACKWASHING will
be displayed in the status box.
C. PARAMETER ADJUST button Touching this button will display the
parameter adjustment screen. This is where changes can be made to the
backwash sequences (Image 3 for Internal Backwash, Image 4 for
External Backwash).
D. STATION STATUS button Touching this button will display the station
adjustment screen. This is where stations may be enabled or disabled.
(Image 7).
PARAMETER ADJUSTMENTS
Parameter adjustments can be made by touching the button at the right of the
field you want to change. The numeric keypad (Image 5) will appear and allow
you to enter a new parameter. The range that can be entered will be displayed.
Below is a description of each button function on the Parameter Adjustment
screen (Image 3 for Internal. Image 4 for External).
A. BACKWASH INTERVAL (M) The Backwash Interval is the amount of
time between automatic backwashing cycles. Backwash sequences will
automatically occur based on this time. Units are in minutes and it is
preset to 240 minutes. Range is 0-1440 minutes. Setting this value to
zero (0) will disable the timed backwash function. (See Image 6).
B. BACKWASH DURATION (S) The Backwash Duration is the amount of
time each station backwashes during a backwashing sequence. Units are
in seconds and it is preset to 10 seconds. Range is 0-30 seconds.
C. BACKWASH WARNING (S) Backwash Warning is the delay between
the backwash sequence request and the start of valves actuation. The
backwash in process relay (RL2) is energized to indicate the sequence
will start. Units are in seconds and is preset to 2 seconds. Range is 0-90
seconds.
D. STATION PAUSE (S) Station Pause is the pause between stations
during the backwashing sequence. Units are in seconds and it is preset to
2 seconds. Range is 0-30 seconds.
E. DP START DELAY (S) DP Start Delay is the amount of time the signal
from the differential pressure switch must be present prior to initiating a
backwashing sequence. Units are in seconds and is preset to 5 seconds
Range is 0-30 seconds.
F. BACKWASH START DELAY (S) (EXTERNAL backwashing systems
only) Backwash Start Delay is the amount of time between taking a
station offline and opening the backwash supply valve. This delay allows
the process fluid to drain from the filter body. Units are in seconds and is
preset at 2 seconds. Range is 0-30 seconds.
G. STATION DRAIN (S) (EXTERNAL backwashing systems only). The
Station Drain duration is the amount of time between closing the
backwash supply valve and placing the station back online. This delay

allows the backwash fluid to drain from the filter body. Units are in
seconds and is preset at 2 seconds. Range is 0-30 seconds.
H. MAIN SCREEN button Touching this button will return the user to the
Main Screen (Image 1 or 2).
I. STATION STATUS button Touching this button will display the station
adjustment screen. This is where stations may be enabled or disabled.
(Image 7)
STATION STATUS
The Station Status screen (Image 7) allows the operator to add or remove
individual stations from the backwash sequence. Pressing the button for the
station to be modified will turn that station ON or OFF. Stations that are ON will
be included in the backwash sequence; stations that are OFF are not included
(skipped). Pressing Next Screen or Back Screen button will cycle to the next or
previous set of stations (when it applies).
FAULT MESSAGES
Below is a description of each fault message on the HMI operator interface. To
reset the system and clear all fault messages and outputs, turn the system OFF
and back ON. The System Fault Relay (RL-1) will be de-energized when a fault
is present.
A. HIGH DP When the system initiates four backwashing cycles due to
differential pressure within 60 minutes, a fault is set and the message
HIGH DP (Image 8) will be indicated on display. Backwash sequences will
occur as normal. Possible causes: plugged elements, insufficient
backwash duration or insufficient inlet pressure to properly backwash the
element.
DIFFERENTIAL PRESSURE SWITCH ADJUSTMENT
The differential pressure switch senses a difference in pressure between the inlet
and outlet piping. When the factory pressure preset has been reached, it triggers
a backwashing sequence. The factory preset is 15 PSID (1 bar).
To adjust the preset, remove the DP switch cover and turn the hex-adjusting nut.
Turn it clockwise to decrease the allowable differential pressure between the inlet
and outlet piping. Turn the hex nut counterclockwise to increase the allowable
differential pressure between the inlet and outlet piping. One flat turn (1/6th of a
turn) of the hex-adjusting nut changes the setting by approximately 2 PSID (0.14
bar).
CUSTOMER INTERFACE
A. GENERAL FAULT (RL-1) This relay is energized during normal
operation. It will de-energize to indicate power loss, system is OFF or if an
HIGH DP condition is present (if there are four differential pressure clean
sequences in 60 minutes). See electrical schematic for connection details.
B. BACKWASH IN PROCESS (RL-2) This relay is energized when the
system is cleaning (backwashing). Reference the electrical schematic for
contact connections.
C. REMOTE BACKWASH SWITCH Use a momentary normally open dry
contact across the Remote Backwash terminals to initiate a backwash.
Reference the electrical schematic for contact connections.
